I'm probably missing it, but how do I set a persistent font size for personal notes on the iPad app? I can't seem to find a way to do this.
If you've added the Notes field to your layout, you can pinch-zoom, then open the document toolbar and click the Save Text Size button, the same as you would with lyrics.
If you're using the Notes button or the Show Notes app control action to show the notes in a popup, you can't change the text size.
